Ports open but High ping

[WATTZ79]

Hi guys ,im currently setting up a few servers on my dedi machine ,when i start a server to test and then look in the browser for it the ping is at 999 ,i have opened the following ports via my firewall

TCP 18390 Outgoing
TCP 18395 Outgoing
UDP 18395 Outgoing
TCP 13505 Outgoing
TCP 80 Outgoing
TCP 19567 outgoing

Am i missing some ports ? if i disable my firewall for a short while my server gets a ping of 23 but when turned back on the server goes back to 999 ping

Your firewall is blocking ICMP packets. Try to unblock them.
